Engine oil„Checking the oil levelCheck the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly insert-
ed until it stops with the graphic symbol
“ ” on its top appearing as shown in
the illustration.
1) Notch
2) Upper level
3) Lower level4. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.
If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.„Changing the oil and oil filterChange the oil and oil filter according to
the maintenance schedule in the “Warran-
ty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, when towing a trailer, or when
driving in extremely cold whether.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine.
3. Remove the oil filler cap.

yUse only engine oil with the rec-
ommended grade and viscosity.
y Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If en-
gine oil gets on the exhaust pipe,
be sure to wipe it off.

4. Open the access cover by removing
the eight clips and turning the access cov-
er counterclockwise. The drain plug will be
exposed.
5. Drain out the engine oil by removing the drain plug while the engine is still
warm. The used oil should be drained into
an appropriate container and disposed of
properly.
6. Wipe the seating surface of the drain
plug with a clean cloth and tighten it se-
curely with a new sealing washer after the
oil has completely drained out.
7. Remove the oil filter with an oil filter
wrench.
8. Before installing a new oil filter, apply a
thin coat of engine oil to the seal.
9. Clean the rubber seal seating area ofthe bottom of engine and install the oil fil-
ter by hand turning. Be careful not to twist
or damage the seal.
10.Tighten the oil filter by the amount indi-
cated in the following table after the seal
makes contact with the bottom of engine.
11.Close the access cover by turning it
clockwise and reinstall the eight clips in
their original positions.
12.Pour engine oil through the filler neck.Oil quantity (guideline):

The oil quantity indicated above is only a
guideline. The necessary quantity of oil
depends on the quantity of oil that has
been drained. The quantity of drained oil
differs slightly depending on the tempera-
ture of the oil and the time the oil is left
flowing out. After pouring oil into the en-
gine, therefore, you must use the dipstick
to confirm that the level is correct.
13.Start the engine and make sure that no
oil leaks appear around the filter’s rubber
seal.
14.Run the engine until it reaches the nor-
mal operating temperature. Then stop the
engine and wait a few minutes to allow the
oil drain back. Check the oil level again
and if necessary, add more engine oil.„Recommended grade and
viscosityOil grade:
ILSAC GF-4, which can be identified
with the ILSAC certification mark
(Starburst mark)
or API classification SM with the
words “ENERGY CONSERVING”
These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container.
API Service label
1) Indicates the oil quality by API designa-tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving ca- pabilities ILSAC Certification Mark (Starburst
Mark)
In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following ta-
ble lists the recommended viscosities and
applicable temperatures.
When adding oil, different brands may be
used together as long as they are the
same API classification and SAE viscosity
as those recommended by SUBARU.

SAE viscosity number and applicable
temperature
*: 5W-30 is recommended.Engine oil viscosity (thickness) affects fuel
economy. Oils of lower viscosity provide
better fuel economy. However, in hot
weather, oil of higher viscosity is required
to properly lubricate the engine.„Recommended grade and
viscosity under severe driv-
ing conditionsIf the vehicle is used in desert areas, in ar- eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM (or SL):
SAE viscosity No.:
30, 40, 10W-50, 20W-40, 20W-50
„Synthetic oilYou can use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this owner’s manual, and must follow
the oil and filter changing intervals shown
in the maintenance schedule.

Use only engine oil with the recom-
mended grade and viscosity.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.
The cooling system has been filled
at the factory with a high quality,
corrosion-inhibiting, year-around
coolant which provides protection
against freezing down to –33 °F
(–36 °C). For adding, use genuine
SUBARU coolant or an equivalent: a
mixture of 50% soft water and 50%
ethylene-glycol basis coolant. Use
of improper coolants may result in
corrosion in the cooling system. It is
important to maintain protection
against freezing and corrosion,
even if freezing temperatures are
not expected. Never mix different
kinds of coolant.

TChanging the coolant
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant is
replaced.
Change the engine coolant and add gen-
uine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule.
1. Remove the under cover.
2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely.
4. Install the under cover.Non-turbo models
1) Filler neck
2) Fill up to this level Turbo models
1) Filler neck
2) Fill up to this level
5. Slowly pour the coolant and fill up to
just below the filler neck, allowing enough
room to add genuine Subaru cooling sys-
tem conditioner in the radiator. Add genu-
ine Subaru cooling system conditioner un-
til the coolant level reaches the filler neck.
Do not pour the coolant too quickly, as this
may lead to insufficient air bleeding and
trapped air in the system.

Automatic transmission fluid„ Checking the fluid levelThe automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid tempera-
ture. Therefore, there are two different
scales for checking the level of hot fluid
and cold fluid on the dipstick.
Though the fluid level can be checked
without warming up the fluid on the
“COLD” range, we recommend checking
the fluid level when the fluid is at operating
temperature.
T Checking the fluid level when the
fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 154
to 176 °F (70 to 80 °C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the selector lever in each po-
sition. Then shift it in the “P” position, and
run the engine at idling speed.
Be careful not to spill manual trans-
mission oil when adding it. If oil
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off.
